TOOTH-BRUSH.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed June 27, 1914. Serial No. 847,655.

To all whom it may concern Be it known that I, CARL A. JACKSON, a

citizen of the United States, residing at Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Tooth-Brushes; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to tooth brushes, and has for its principal objectto provide a fountain tooth brush wherein a dentifrice may be stored inthe handle of the brush and fed to the head and bristles as required.

It is also an object of the invention to provide a brush of thischaracter with a removable handle, so that when the dentifrice hasbecome exhausted, the handle may be removed and refilled or replaced. 7

In accomplishing these objects, I have provided improved details ofstructure, the preferred forms ofwhich are illustrated in theaccompanying drawings, wherein Figure I is a perspective view ofpa brushembodying my mvention. Fig.'II is a lon- 'tudinal, sectional view of thebrush. Fig. II is an enlarged sectional view, indicating the delivery ofdentifrice to the bristles. Fig. IV is a sectional view of the handle.

Referring more in detail to the drawings: 1 designates a tooth brushconstructed according to my invention and com rising a brush head 2,provided with brist es 3 and having an interior chamber 4.

The head 2 has a plurality of orifices 5 opening therefrom amongthebristles 3, to provide outlet for the contents of the'chamher 4, and isprovided, at one end, with a threaded neck 6, having an aperture 7therein communicating with the chamber 4, and having exterior screwthreads for application to the interiorly threaded neck 8 of a handle 9.

The handle 9 preferably comprises a sub stantially rigid member 10 forforming the top and sides thereof and a soft under portion 11 clampedthereto and forming a tube,

for containing a dentifrice 12 in the form of the soft under portion ofthe handle is compressed, thus forcing the dentifrice through theapertured neck portion into the chamber, where it is emitted through theorifices among the bristles and is applied to the teeth. After all thedentifrice has thus been discharged from the handle, the handle may beremoved and refilled or replaced by a new handle.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters-Patent, is:

In a tooth brush having a hollow head provided with an exteriorlythreaded tube and a plurality of apertures, a handle comprising a rigid,channeled body having an end duct threaded onto said tube, and arelatively soft membrane seamed to the edges of said channeled body, forthe purpose set forth.
